Dstv internet has made my life a living hell

I have spent 7 days without being able to connect, I have moved to my current address from Oct 2024. I was connected up until I started experiencing problems from the 13th January 2025,today on the 20th went to dstv Centre when I got there they inserted their Sim card the rooter worked the light was blue when they changed the Sim card to the new one they giving me, the router stopped connecting light turned green, I have called your call Centre but no one seem to be able to come up with solutions, this has hold me up in doing my work. You can imagine 7 days of calling their call Centre waiting holding up for hours and the cost of buying data when you have a contract that is supposed to supply u with data. I'm fed up and unsatisfied with their product and support system.
